T0015 whom it my concern.

Be it known that I; HENRY R. STOLL, a citizen of the United Statesresiding'a't-El Peso, in the county of El laso and State 5 of Texas,have invented certain new and useful Improvements in Strainers for Sinksand the like, of which the following is a specification.

This invention relates to improvements a in strainers for sinks washbasins, laundry tubs, bathtubs, and in fact all similar plumbingfixtures. 7

One disadvantage presented by the majority of straining fixtures of theclass mentioned is that the solid waste matter col lected and retainedthereby must be removed by the fingers or in some other nconvenientmanner and therefore the present invention has as one of its objects toso N support the strainer member that the same may be readily unseated,the accumulations therein readily dischar ed, and the. said memberreadily cleaned efore replacement,

'thus'enabling the cleaning. of the strainer to be. efi'ected in a moresanitary and thorough manner.

I The majority of straining devices of the class referred to alsopresent the disadvantags that their perforations are liable to be- 30come clo god with grease or similar waste matter t us interfering withthe draining oil of the waste water in the sink, and therefore thepresent invention has as a further object to rovide means whereby theperforations 0 such accumulation in. a convenient manner and without thenecessity of removing or "dis lacin the strainer.

fort er object of the invention is to provide for the removal andcleaning of the strainer so that the accumulation of use and similarwaste matter upon its under side may be prevented, andthe fixturetherefore kept in a more sanitary, condition.

In the accompanying drawings:

Figure 1 is a'view in elevation of the fixture embodying the inventioninstalled in a kitchen sink;

Figure 2 is a detail diametric sectional ls shown in Figure 1; and

\ Figure. 3 is a diametric sectional view i taken in a plane at right anice to the plane of'Figure 2 and through t the strainer may becleaned-ofsuch f view through the fixture mounted in place v mannerfirmlg supported wlthln the upper e strainer and.

In the drawings the fixture embodying the invention is illustrated asemployed in connection with a kitchen sink but it will be understoodthat it may be installed in'otherplumbing fixtures of asimilarfcharacter. The sink is indicated in general by the numeral l.and its bottom by the numeral 2,

the said bottom being formed at a suitable point with a circular opening.3 and in its upper side with a rabbet or countersink 4 which surroundsthe said openin as is usual in such fixtures. The fixture em odying theinvention comprises a body which is indi- 'cated by the numeral 5 andwhich is of cylindrical form and exteriorly threaded as at I 6. Thisbody is provided exteriorly at its upper end with a circumscribingoutstanding flange 7. having a portion turned upwardly as at 8 and aportion directed out-. portion 8 of the flange wardly as at 9. The 7seats snugly within the opening 3, and'the portion}? in the countersink4. A rin nut 10 is threaded onto thebody 5 and is a a tedto be tlghtenedto -bear against the un er side of the sink bottom 2 as best. shown. in

Figures 1 and 2 of the drawings, to bind the flanged upper end of thebody 5 firmly to the said sink bottom and within the open ing 3. Thewaste pipe which leads from the sink and conducts the waste water isindicated by the numeral 11 and the'same is coupled by a con ling nut 12withthe lower end of the b0 y 5 as'shown in Figure 2. T l

The strainer of the fixture is indicated in general by the 'numeral 13and the same comprises a-bowl 14- preferably of hollow semi-sphericalform althou h it may be made shallower if found esirable. The

strainer bowl is provided substantially throughout its area witha numberof perforations 15 through which the wastewater may flow but which willnot permit the we sage of any solid waste matter in particles of size aswill be liableto clog the waste pipe 11. At its upper ed 0 the bowl14 isprovided with an outstan ing circumscribr in flan e16 which rests uponthe upper eide of t e flange 7 inwardly of the upstandm in igure 2, thestrainer bowl being in this end of the b0 l Within the strainer bowlthere is arranged a scraper member, adapted to be manipulated ortion 8of said flange as clearly shown similar waste matter accumulating uponthe inner side of the bowl and interfering with the passage of the wastewater through the gerforat-ions 15. This scraper member is in-- icatedin general by the numeral 17 and the same comprises a blade 18 which isof arcuate form and of such length and so curved from end to end as tofit within the bowl 14 and extend circumferentially of the inner surfaceof the wall thereof. The blade .18 is preferably beveled upon its innerside at its opposite ed es to form scraping or shearing edges indicatedby'the numeral 1 9. A cross bar 20 extends transversely between the endsof the blade 18 and may be integ" rally connected therewith or securedor connected thereto in any desired manner, and

this bar is provided at its ends with small trunnions 21 whichfit inbearing seats 22 formed at diametrically opposite points in thecircumference of the top of the bowl 14,

- ner surface of the wall of the bowl and re-.

the member 17 being in this manner suspendedxby its upper corners foroscillatory motion within it e bowl and so that in such motion its edges19 may scrape over the inmove any acccumulations upon said surface.

The cross bar 20 constitutes a means whereby Y the scraper member 17 maybe oscillated in the manner and for the purpose stated, it being onlynecessar to rotate this bar between the fingers in or er to effect suchmovement v of the scraper blade. Also the bar constitutes a handlemember whereby the strainer as a whole may be lifted from its seatwithin the upper end of the body 5. In order that the strainer, afterits removal may be conveniently held in the hand while being cleaned, afinger knob 23 is preferably provided upon the under side of the bowl 14at the central portion thereof.

The stopper of the fixture is. indicated in general by the numeral 24and may be formed from any material found suitable for the purposeandpreferably comprises a fiat circular body 25 the marginal portion 26 ofwhich is adapted to seat more or less snugly in the opening defined bythe portion 8 of the flange 7 and .to rest uponthe upper side. 7 of theflange 16 of the strainer bowl. A finger ring or the like indicated bythe numeral I 27 may be provided upon the upper, side of the body: 25 ofthe stopper to provide for its convenient handling in fittingit intoplace and removing it.

When the stopper 24 is to'be employed,

re eases bowl and out through the waste pipe 1.1,

solid waste matter being collected and ietained however within thestrainer bowl from which it may be conveniently discharged, after all ofthe water has been drained away, bylifting the bowl out of place anddumping its contents, At such time the bowl may be readily cleaned andthen refitted into place. if there is no considerable accumulation ofsolid matter and should the perforations 3.5 become fouled or clogged,this condition may be remedied by rotating the cross bar 20 back andforth between the fingers thus imparting a swinging motion to thescraper member 17 causing its scraping edges 19 to move over the innersurface of the wall of the .bowl.

Having; thus described the invention, what is claimed as new is:

1.. in a device of the class described, a

body, a strainer arranged within the body and comprising a perforatedbowl, an arouate blade supported for oscillation within the bowl to bemoved over the inner surface of the bowl, and a cross bar extendingsubstantially chordal to the blade and constituting means wherebyoscillatory motion may be imparted to the said blade.

In adevice of the class described, a body, strainer disposed withinthe'body and comprising a perforated bowl, and a scraper for the bowlcomprising an arcuate blade, a cross bar extending between the ends ofthe blade, and bearing elements at the said ends of the blade and barpivotally seated in the wall of thebowl whereby to suspend the blade foroscillation.

.3. in a device of the class described, a

body, a strainer disposed within the body nanny n. s'roLt. a a]
